This invention relates to a hinge well adapted for upwardly acting sectional doors and the like.

The main objects of this invention are: I

First, .to provide a hinge which is well adapted for upwardly acting sectional doors and the like which permits the hinge members being fixedly mounted on the door sections at the factory or other convenient place of assembly and the sections being quickly assembled, at the place where thedoor is installed. ,0

Second, to provide a two part hinge comprising coacting knuckle and pintle hinge members, each ofwhich is formed as a unit desirably from sheet metal stock of uniform thickness and at the same time the hinge is provided with effectively coacting knuckle and pintle.

Third, to provide a sectional door assembly comprising a plurality of hingedly connected sections provided with hinges which are highly effective in resisting lateral thrust on the door sections.

Fourth, to provide a hinge embodying these advantages which may be very economically produced and at, the same time is capable of withstanding severestresses.

Objects relating to details and economies of the invention will appear'from the description to follow. The invention is defined and pointed out in the claims.

A preferred embodiment of the invention is illustrated in the accompanying drawings, in which: I I

I have illustrated my invention embodied in an upwardly acting door comprising a plurality of hingedly connected sections 1 which are provided with a, plurality of 'knuckle or female hinge members 2 on their upper edges and coacting male or pintle members?) on their lower edges. Tracks 4 are conventionally illustrated Fig. l, the sections being provided with track engaging rollers 5' at each 'end thereof.

Drums'6 are provided for the cables 7, the shaft 8 ofthe drums being torsioned by means of the spring 9. I have not described the details of the track and cable windingdrums astheyzform no part of my present inven-' tion. M

The knuckle hinge member 2 is formed integrally of sheet metal stock and comprises an attaching leaf with holes 10 therein adapted to receivev attaching elements 11. The leaf or body portion of the hinge mem ber has an outturned flange 12 on its upper edge termlnating in a curved inwardly facing knuckle element 13. A curved coacting tongue-like knuckle element l4 -is struck out from the body and flange of the member 2 and concentrically disposed relative to the knnckle elee ment 13. The edge 15 of the knuckle; element 14 is, spaced from the edge 16 of the knuckle element 13 providing a slot-like opening to facilitate the assembly and disassembly of the hinge members as will be,further' pointed-,out. I, e s

The pintle hinge member -3 is also formed as an integral sheet metal stamping and is provided with a leaf or-body portion having holes 10 therein adapted to receive attaching elements 11. The member 3 has an outturned flange 17 on its inner edge terminating in, a curved pintle element 18. This hinge element 18, in

theembodiment illustrated, is 'approximately 270' de-- grees in extent. The complementary pintle element 19 is struck up from the flange of the pintle member 3 and concentrically disposed relative to the pintle element 18 coacting ttherewith to provide a cylindrical pintle. The,

striking or forming of this pintle element 19 from the,

sult in the operation of the door, the hinge members may be engaged by relative axial movement and when swung to normal operative relation thetongue-like knuckle ele-. ment 14 passes through the opening 20in the pintle member thereby preventing relative axial movement of the. hinge members. i

When the sections of the door hingedly connected by. the hinge members of this invention are inalignment the flanges 12 and 17 of'thehinge members are in sup-- porting engagement. width also serve as reinforcingmeans for the hinge members therebypermitting their being made of sheet metal stock and at the same time theyare capable of carrying substantial loads and resisting substantial stresses.

The-door sections are desirably provided with these hinges positioned at the edges of the door and also withintermediate hinges as illustrated in theaccompanying drawing. The hinges may be mounted on the door sections at the factory or other place of assembly and the sections shipped or transported and quickly and easily assembled at the place of installation of the door. This not only insures the hinges being positioned in the desired rnanner but permits their being secured by rivets 11 which is not very practical to do when the hinges are mounted on the sections at the place of installation of the door.-

I have illustrated and described my invention in a.

embodiments which I contemplate, as I believe this dis-- closure will enable those skilled in the art to embody or adapt my invention as may be desired.

Having thus described the invention, what is claimedas new and is desired to be secured by Letters Patent is:
